After doing some searching I understand that the engine displacement stamp is supposed to be above the fuel pump on the block. Mine, however, is not. The Scout I just bought has what looks to be a rebuild or nos replacement engine, as it is painted black and looks fairly clean (definetly not from 1970). It has a large vacuum "tree" on the back of the intake with about 5 vacuum ports on it and what looks like a factory block off plate where the fuel pump goes. On the block where the engine id is supposed to be it's just got 3 large random numbers. Any ideas on what I might have?
